Are ghosts of deceased people might not have symptoms, but lively aliens?

 
I do not think the ghosts are aliens, but that the good aliens have techniques to make themselves invisible, as their ships!

Their techniques could be more than useful to us. Only we will not get them to face as long as there are stillwars and we behave like the primitive Neanderthal mutually erschlegen stick with NEM. Since it does not matter whether or nuclear rocket stick. the effect is indeed the same. And why not give such a Zivilistiontechniques? In order to perform well even in space and wars to bully other life forms?

Maybe even the one that would allow us the technology? So that's really stupid is no alien.

In religious terms, the more evidence there is more between heaven and earth as the little man's mind can ever imagine.

But when you chase every UFO shoots rocket with Starfighters and laugh at the. Grinning because they canavoid going so fast they laugh about it, so it's not appropriate or welcome?
